The main shaftI 6 carries the coin `carriers 7-'8+) of which there may be any number. In thepresent case three are shown, 7 being `for 5 cent pieces, 8 for 10 cent pieces,`,anl 9 for 25 'centpcces, except for difi'eren'ces .in dimensions as is required'for coins of different denoniinations the vcarriersv are i'deiitical in shape. They consist each Of two side' arms '10 carried by shaft 6, the inner Vsidesfof the tops of which are furnihed with grooves 11 for engaging and holding opposite Vsides Vof the coin. In their normal.l position 4the grooves 11 are opposite and` in registerv with `the slots 1211i the vcasel through which the coins are passed to the'machine. Shoiild a coiniof improper denoinination'be passed through one of the slots 12, a v10`cent or a 5 cent coin be passed into the 25 cent .slot for instance, its opposite. 'sides'willinot be simnltaneouslyen'gaged by' the grooves 11 in the' 25 ceiit carrier 9`and the coin will falldown between the arms 10 of this carrier, ``will drop u on the slide 13,'Fig. .1, andwillpass' out of tlie casel through a slot 14 and l,Will be returned to the operator. If'lthefcoiii be of ,an acceptablev size'its oppositeedgesjirill be held by the slots .11 andit willpass down these-slots until it is engaged by a holder 15 which is. fast to a shaft 16,. '1`here'isa'eparate holder 15 for each coin carrier while 'they all perform the same Ifunctiontliey are operated shaped so that each will cause a ditferei'itfrotation of the' shaft 16 for an equalthrow of the shaft 6 which carries the coincarriers 10'; vthis unequal rotation of the shaft 16 being necessary in order to cause 'the' alarm ringing 'mechanism, which is actuated through the movements of shaft 16, to sound o separate alarms or signals for the several coin carriers. i

The normal position of the several coin carriers 10 and of the coin holders 15 is shown in full lines in 14`igs. 3, 4 and 5. 17 shows in each figure a central cross section. of the coin in each holder and, as before stated, the carrier shown in Fig. 3 is for 5 cent coins,

that shown in Fig. 4 for l 0 cent coins, anav tinthe utility of this arrangement will be' apparent.

an acceptable coin be passed through one of the coin slots 12 in case 1 to one of the carriers 10, it will slide down the grooves 11 in the carrier until its movement is arrested by its engaging the point 18 of the holder 15. The telephonereceiver being lifted from its hook,` presently'to be described, the operating lever 2 of the machine is rocked causing, through pinions 4 and 5, a lrocking of shaft 6 and coin carriers '10 towards the holders 15. Th'e coin carried by one of thecarriers and held therein by the point 18 of the holder 1'5 acting in connection with this carrier now rides over the point 18 and, as the carrier is further turned, its upper face resently engages the upper point 19 o the holder 15 and a further movement of the carrier 10 causes the coin to bear against and push backward, the 'point 19 and the holder 15 causing the shaft 16"'to turn ,upon its axis until the lever .2 has been thrown to the full extent of its stroke. During this movement the holder 15 has lbeen moved'until it takesl .23 the function of which is to check the return movementof the shaft 16 after its operation by a coin as described, the rotation of 'the shaft 16 winding'up a spring 24, Fig; 2, the unwindin'g' of'wh'h returns the shaft 16`and connected parts tol their original position; To shaft 16 is secured a ratchet 25, Figs. 2 and 7, having as many teeth as there are coin carriers in the machine, in the present case three.

26 is a spring pawl pivotally carried by a Striker 27' which is pivotally supported upon a stud 28. Upon an upward movement the teeth of ratchet 25 engage and 'move the tooth of pawl 26 out of their path, upon a downward movement of the ratchet 25 its teeth engage the tooth of pawl 26 and press-` ing down upon 'this tooth cause'it and the pawl to rotate the strikerv27 upon its pi'vot 28. As soon as each tooth of the ratchet t passes the pawl a springe29 suddenly'returns the Striker to its first position `and` causes it to engage and ring a gong' 30. As

before stated the shaft 16 is rotated-'t'o dif- I it is essential that each movement of the Operating lever 2 be a complete one, a partial movement of thislever'results in an incomplete cycle of movements in the machine and '3 may serve to seriously disarrange it. In order that the lever 2 may have to'be moved to its full stroke before'returning to its initial position, we have devised the' simple and efiicient stop shown in Fig. 6. pinion, 5 is engagedf by a detent 31 which is rotatably carried upon a pivot 32 and mai'ntained in an operative position by a spring 33. At points corresponding with the ends of the throw of the pinion 5 one or more teeth are removed, 'as at 34-35, so as to permit the detent 31 to change its direction at these points. If the detent be in the opening 35, as shown inl Fig. 6, and the lever 2- be moved to the left the top of the pinion 5 will be moved to the right and the-top of the detent to the left and its lower end w'ill drag over the teeth of the pinion. i'

' If the movement of the lever 2 be arrested The i, 'i

before completing its entire stroke the detent "I 31 will engage the teeth of the pinion 5 and prevent it reversing its movement thus locking the lever 2 against a return movement.

When the detent 31 reaches the opening 34, at'which point the lever 2 has completed. itsy stroke, its direction can change so as to permit the return of the several parts'to their first. apositions. In other words the detentv 31 prevents a reverse movement of the leve:` 2, in either direction, until it has completed its full stroke.

In private homes, particularly, -the operatng lever of a call box is frequently operated by children as a form of amusement. I?? order to preventfthis abuse of the machi'zfz;

wel1avef11rnished .a :lock` for i this 3 lever which is as' followsze-The end of. the shaft 6 ladjacent to the zhookflwhichacarries ythereceiver'? is furnished with 'a notch 38a `Fig.l l2,-.which is adapted to be engaged,

f when the hook is depressed bythe'weight of thereceiver; by` an arm 39 which .is rigidlyfi' attached to the shaft 40 to-which the'hook -36 is rgidly 'attached 41 lis aspring for lift-ingthe'hook 86 and the arm 39 when the receiver is lifted from the hook. Then the rcceiverl 37 is upon the hook 36 the arm 39 'is'lowered so vthat it engages the notchBS int shaft 6 preventing any rotationthere'of until' the receiver .and hook be'lifted. The inner end of the arm 39- forms, in connection with' va spring 412.` the switch for automatically .connecting the .current upon the lifting of the recciver and for automatically breaking it upon placing the receivcr'onthe hook. The inner end of the arm is bifurcated ;upon lifting the receiver the part- 43 of the arm` engages the spring 4-2 and causes it to engage plate, thus completing the .circuit.

When the ou'ter end of lthe hook 36 is lowered `by the weight of the receiverthe part-'43 of `vthe arm 39 is moved away from the spring `12 and in order that' the spring may betposl-` tivel.v lifted from thev plate let' the lower end 45 of th'e arm carriesan insulatecl pin 40 engaging the uncler side of'the pin and lift-'f ing it clear'of' the plate 'when the receiver is placed upon the hook.v This feature of our invention will form the subject of'a 'separate' application for patent.
